In reply to thespecialone:
I don't know about that area but my wife and I were travelling by PT in northern Italy near the lakes and had booked an AirBnB in an Italian town. Got off the train and went to the taxi rank, no taxis, waited, none came, rang the number given, no answer. Back into the station to look around for any taxi info, none found. We finally got a lift to the place from going into a shop and asking around, the shopkeeper instructed one of his customers to give us a lift as he lived in the right direction.
